Hey guys, I made a little tool for JSTris to help improve your sprints. It's basically the sprint coach feature from Nullpo in the form of a Chrome Extension for JSTris. What it does is change the color of lines remaining based on how fast you are currently playing. This gives you some visual feedback on when you need to push harder or just give up and restart.

How to install:

I don't want to pay Google $5 to host on the chrome web store, so you'll have to just download the file and install it manually.

1) Download the .crx file here.2) Go to chrome://extensions/ in your browser and drag the .crx file in. You should see this:

How it works:

Click the little icon by the URL bar (or in the Chrome menu) to access the settings. (Note: The extension won't do anything until you setup your settings.)

Sprint Lines is just what mode of Sprint you are currently playing - for 40L set it to 40.Goal time is the time you are aiming for.Extra pieces is how many pieces over the lowest possible you are aiming for. I set this to 1 since I can rarely finish sprints with a PC. A setting of 2 is probably also reasonable.Best PPS - set this to the global speed of your fastest sprint, or the fastest burst you have achieved. The coach uses this to determine when to tell you to speed up.

Once you have it set up, go to Sprint mode on JSTris (note: you'll need to be at https://jstris.jezevec10.com/?play=1 for it to work, it won't work from the practice menu on other pages - I'll fix this in the next version). You should see the number of lines change color. What the colors mean:

White You are going fast enough to meet the goal time.Yellow Your current speed is too slow to meet the goal, but if you speed up to your Best PPS you could make it.Red It's impossible to meet your goal unless you can go faster than Best PPS.Dark red You've passed your goal time already.

Hopefully someone will find this useful! Let me know if you have any questions - I'm on the Harddrop Discord as "pwn".

Edit:

Updates:

Version 1.01 (10/3/2017) - Extension should now work on all language subdomains.

Hi pwn, is the source code available? Any plans to submit it to the Google Chrome Webstore?

Maybe a little known fact, but .crx files are just a ZIP archive, you can extract the source with any archive manager (you may have to rename it to a .zip to get it to open.) I'll probably end up putting it on Github at some point but for now you can view it this way.

Google charges you $5 before you can upload anything to the web store, which I don't really want to pay unless this gets significant interest or not having it on the web store is a real impediment to people being able to use it.

It's not working for me unless it gets uploaded to the webstore. Let me PayPal you $5 to get it up. PM me your paypal.
